ANDREW A. SEBULA, OF SOUTH MANCHESTER, CONNECTICTl'T.

PERMUTATIon-LocK.

To all whom it may concern:

Be it known that I, ANDREW A. SEBULA, a subject of the Emperor of Austria-Hungary, residing at South Manchester, in the county of Hartford and Stateof Connecticut, have invented certain new and useful Improvements in Permutation-Locks, of which the following is a specification.

This invention relates to certain new and useful improvements in permutation looks.

The primary object of this invention is the provision of a casing lock adapted for securing a keeper by means of a permutation controlled locking bolt adapted to be released by a specially designed form of releasing means, thereby preventing a retracting of the bolt by a person unfamiliar with the lock and even after the proper manipulation of the permutation members;

A further object of the device is the provision of a lock having a normally projected bolt retractable only upon the proper setting of permutation members accompanied by the separate actuation of a safety catch for the bolt, the said device being readily tripped as well as released by a person familiar with the operation of the look.

For accomplishing these objects, a permutation device is arranged adjacent the normally projected bolt and a turn device for retracting the bolt when the permutation members are properly positioned is prevented from operation by a bolt engaging catch which is tripped into-engagement with the bolt when the latter is projected and is also releasable upon the proper ma nipulation' of the said retracting means, the manner of operating the same being difficult to ascertain by any person unfamiliar with the lock mechanism. I

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the combination and arrange ment of parts hereinafter more fully de scribed, illustrated in the accompanying drawings, and pointed out in the appended claims.

lar view with the bolt retracted. Fig. 5 is a view similar to'Fig. 3 with the retracting device as normally positioned and about to trip the bolt engaging catch, the latter being shown by dotted lines in its tripped position. Fig. 6 is a longitudinal sectional view taken upon line VI-VI of Fig. 5. Fig. 7 is a transverse sectional view taken upon line VII-VII of Fig. 4. Fig. 8 is a sectional view taken upon line VIIIVIII of Fig. 3, and Fig. 9 is a detail view of the bolt releasing means and with the adjacent portion, of the casing shown in section.

Referring more in detail to the drawings, a casing 10 is provided forthe lockimechanism having a removable rear plate 11, while the, front plate 12 of the casing is provided with a keeper receiving opening 13. A locking bolt 14 is slidably mounted in brackets 15within the casing 10 and is normally held projected over the keeper opening 13 by means of a spring 16 which connects the forward one of the brackets 15 witha flat plate extension'17 upon its inner end, the outer edge 18 of the said extension acting as a stop for engaging the inner bracket 15 to limit the extent of projection of the said bolt. i 7

The front plate 12 of the casing is provided with a dial 19' and a shaft 20 is centrally journaled therethrough, and extends through the casing being journaled in the casing and in a bearing plate 21 mounted therein. The shaft 20 is vprovided'with a turn knob 22 exteriorly of the front plate 12, while a star indicating wheel. 23 is mounted upon the shaft 20 adjacent thereto and overlying the dial 19 whereby the desired extent of rotations of the shaft 20 may be ascertained.

The shaft 20 is provided with outer and inner permutation members 24 and 25 respectively in the form of gears and having their toothed peripheries 26 lying-in the retracting pathof movement ofthe bolt extension 17 whereby thebeveled inner end 27 of the said extension will engage the teeth 26 of the two permutation members in the event that the bolt is partially retracted during the'normal locking position ofthe said permutation .members.

an open slot 28 through itsxperipheral rim and it will be apparent that when the said :slots 28 {of iboth of the permutation members are brought vinto idire'ct alinement with the bolt plate'17, the 'boltupon being retracted will allow :the saidiextension 17 to freely passthrough the said. slots .28 andwhereby the permutation members will offer no -0bstruction to the unlocking-of the bolt. A

dog 29 islpivoted to the bearing plate 21 and has its angular end 30 ratchetingly engaging theteeth 26 of the inner permutation member-25 .whereby the said member 25 may only revolve in one direction, being restrained by the dog-member 30 from re:

I '1' permutation member 25 which lattenmember is freely j curnaled upon the said shaft 20. l he hub 32 ha's an-Linclined free face 33 upon which the pin 31 is' adapted to ride when'sthe member -24"is revolved in one direction and at which time also the dog mom ber'30-prevents a rotation of the-member 25. then themember 24=is revolvedin an opposite directionythepin .31 engages the squared end 34 of the hub 32 and carries the other member 25 around with the same and in which. direction the dogwmemb er '30 freely ratchetsoverthe teeth of the said member 25. An expansion spring 35 is arranged between the plate 21 and 1 the I adj a'cent face of theipermutation :member 25 which resilwiill zthus-be evident :that the-permutation knob 22- is first rtiirned .in' the x direction indicated hy' the arrow fin Fig. 1 foraccurately positioningthe slot 28. of the inner permutation .member 25 in releasing alinement '5 with {the bolt platet17, :the said :member 25 illiLlSg'HlOVBd in the y direction indicated by the arrow in (Fig. 3'2. and having thus so positioned this iinember 25', the knob 22 is thenturned in a reverse directioniuntilithe'slot" 2.8 of rthe" outer, perm-teammate 12.4 is

p Each of the said member's24 and25'is provided with likewise positioned in alinement with the bolt extension 17 it being understood that such adjustments are made to agree'with the predetermined registering of certain teeth of the indicating wheel 23 with points upon the dial 19. 4 I

A connecting catch 36 is slidably mounted within a bracket 37 within the casing 10 being normally influenced to project obstructingly inwardly of the adjacent side shoulder38 of the bolt 14 by means of a spring 39 connecting an angular end 40 of the said catch with the inner bracket 15 heretofore referred to. A spring plate 41 incloses the said an'gularend 40 and is provided with a depending lug 42 adapted to connect behind ;a shoulder 43 ofthe catch 36, when the said catch is in its retracted releasing position as illustrated in Fig. 5, while a .release of the catch 43 allows thespring 391130 project the catch 36 to its bolt engaging position as illustrated in Fig. 2.

A bolt retracting and latch actuating means is provided consisting of a turn handle 44 arranged upon the front plate 12.01 the casing and having an inwardly projecting post 45 journaled in the casing side, while a latch 46 is pivoted as at 47 .to the said post and is normally retained elevated by means of a spring 48. The inner end of the spring 41 is inwardly turned as at 49 being V-shaped and terminating in a point 50, while a stepped stop lug 51 isrposit'ioned upon the side of the casing and lies adjacent the spring end 49.

' With the catch 36 released as shown in Fig. 5, aturn of the handle 44 in the direction indicated in Fig. 1, moves the latch '46. with its beveledreduced end 52 betweenthe springend 49 and stop lug 51, thereby separating the said members sufficiently to release the-lug 42 from its engagement with the catch shoulder 43, thus allowing the catch to move to its engaging position, as shown in 'Fig. 2. After'this release of :the catch 36 the latch 46 will spring beneath and ratchet past the catch end 240 and may continue this movement and in a similar mannerpass beneath the arm '53, of the bolt 14, the latch 46 being slightly depressed'by the said arm and engagingthe lower beveledend 54-;thereof. The elements willthen be positioned as illustrated in Fig. 2 which T is-the'normal locked position of the bolt by both the permutation members as well as the catch 36.. A

It will be understood that a staple 55 or any other desired form of'keeper is adapted r to be positioned Zthrough :the front plate opening 13=of the casing which will be-engaged by the locking bolt 14 as illustrated in Fig. '6. When desired to release "the keeper, sthe elements being found "flSilllUS-' trated in Fig; 2, the permutation members are operated by the knob 22 in the manner heretofore set forth to their'releasing positions as shown in Fig. 3. The handle 44 is then turned for ratcheting the latch 46 beneath the spring end 49 and thecatch end 40. A slight reverse movement of the-handle 44 then engages the latch 46 with the catch end 40 and retracts the same until the lug 46 automatically engages the catch and retains the same retracted and in which position the stepped shoulder 56 of the stop lug 51 prevents a further reverse movement of the latch 46 all as illustrated in Fig. 3. The handle 44 then continues its movement further for moving the latch 46 beneath the bolt arm 53 and after passing the said arm, the handle 44 may be moved in a reverse direction which will engage the latch 46 with the said arm 53 which will thereby retract the bolt as best illustrated in Fig. 4.

It will be understood that the present device is adapted for use not only in connection with the form of staple keeper 15, but

may be readily arranged to engage the usual form of door keeper (not shown) by projecting the locking bolt 14 through an opening in the adjacent side of the casing 10.

The form of device now set forth may be readily employed in connection with mail bags and strap locks and other similar devices, and it will be seen that it is necessary for a successful operation of the lock that the operator be familiar not only with the correct combination for the permutation members, but also with the required movements of the catch releasing means actuated by the handle 14. a

While the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor changes may be made without departing from the spirit and scope of the invention as claimed.
